Timeline of Fate, Ep. 7 – Queen of the Nether Realm

Episode 7 of the Tartrus of Oblivion chapter — Pure Vanilla Cookie descends into the realm of the crumble in search of the answer he lost.

Ghosts haunt the halls of Blueberry Yogurt Academy. Uncover its hidden past through the memory fragments someone left behind, and having faced the truth, follow Pure Vanilla Cookie into Tartrus — the realm of the crumble. Ep. 7, Queen of the Nether Realm, is released first in this update and can be played without clearing previous episodes; Ep. 8 follows in the next update.

Episode Effect: Consuming Memories
  • The Consuming Memories effect applies starting from the Dusty Bookshelf stage.
  • Attacking enemies or taking damage fills up the Consuming Memories bar. Allies whose bar is full fall into Sleep, take increased damage, and gain the Dismay status, which permanently blocks Healing and Shields.
  • The Ruler of the Nether Realm, Nether Queen Cookie, is immune to Consuming Memories and can grant Shields or Heal allies with the Dismay status.
  • Defeating enemies imbued with the Nether Realm's energy will restore the HP of allies who have gained the Dismay status.
  • Asphodel Cookie, who wanders the Nether Realm, gains increased ATK and DMG Dampening, greatly slows down the rate at which allies' Consuming Memories bars fill up, and applies the buffs to all allies.
Tactical Skill: Bell of the Nether Realm
  • The Bell of the Nether Realm tactical skill becomes available starting from the Failed Binding Spell stage.
  • The bell tolls, clearing the Consuming Memories bar and Dismay status from all allies while dealing damage to enemies and putting them to Sleep.
  • If Nether Queen Cookie, the Ruler of the Nether Realm, is on the team, allies deal increased damage.
  • Defeating an enemy imbued with the Nether Realm's energy adds a Tactical Skill charge.

Trials of the Nether Realm

A seasonal endless exploration mode — lead your expedition through the Nether Realm and go as far as you can.

Trials of the Nether Realm is a seasonal endless exploration mode where designated Cookies explore the Nether Realm based on each season's featured element. Choose your path at each fork, manage your Cookies' Activity Points, and push as deep as you can for Legendary Topping Tart materials and seasonal rewards.

Difficulty
  • Two difficulty levels are available — select the one best suited to your current progress.
  • Easy: a relatively light challenge with a maximum of 5 areas.
  • Hard: a grueling challenge featuring an endless series of areas.
Seasonal elements and Cookies
  • Seasonal Element Restrictions: each season features 3 designated elements, and expeditions can only be formed with Cookies using those elements.
  • Season Cookies: Cookies featured each season receive powerful special effects in the Trials of the Nether Realm.
Expedition Cookies
  • Additional expedition slots can be obtained from Area Clear Rewards.
  • Slots expanded during the current run remain unlocked for your next run.
  • Rarity Restriction: only one high-rarity Cookie (WITCH, BEAST, LEGENDARY, ANCIENT, DRAGON, or SUPER EPIC) can be placed per run.
Nodes
  • Battle Nodes: battle regular enemies. Progress is saved after each wave, so a failed attempt resumes from the last wave reached.
  • Fierce Battle Nodes: battle elite enemies. The enemies' remaining HP is saved, so you can retry from where you left off. When a Cookie enemy appears you can recruit that Cookie to your expedition party — recruited Cookies do not take up slots and leave before the next expedition.
  • Healing Nodes: restore a Cookie's Activity Points, or the AP of the entire expedition.
  • Rift of Oblivion Nodes: a Battle Node, Fierce Battle Node, Healing Node, Cookie Ally, or Reward appears at random.
  • Boss Nodes: battle the boss enemy, whose remaining HP is saved between attempts. Bosses await on the final floor of each area — clear the floor to move on.
Cookie Activity Points
  • Cookies that participate in battle lose Activity Points after the battle ends.
  • Cookies with no AP remaining cannot participate in battles until the end of the current run.
  • Activity can be restored at Healing Nodes, or through Rift of Oblivion Nodes at a certain chance.
Rewards and Time Jumpers
  • Area Clear Reward: clear the Boss Node in the current area to earn this First Clear Reward once per season.
  • Node Rewards: reach reward milestones in the current area and claim rewards once per season.
  • Battle Rewards: earned by winning in battles.
  • After playing a specific difficulty and ending your expedition, Time Jumpers let you earn Battle Clear Rewards based on the deepest zone you have reached during the season.
  • If multiple records share the same furthest cleared zones, rewards are based on the most recently cleared Battle Node. Uncleared zones are not included, and reward amounts vary with the number of Battle Nodes cleared.
  • Rewards obtained by using Time Jumpers do not count toward your score.

What's New
Timeline of Fate: Tartrus of Oblivion Ep. 7 — Queen of the Nether Realm

Ghosts haunt the halls of Blueberry Yogurt Academy — uncover its hidden past through the memory fragments someone left behind. Having faced the truth, Pure Vanilla Cookie ventures to Tartrus, the realm of the crumble, in search of the answer he lost. Ep. 7, Queen of the Nether Realm, is released first in this update and can be played without clearing previous episodes; Ep. 8 will be released in the next update. The Consuming Memories Episode Effect applies starting from the Dusty Bookshelf stage: attacking enemies or taking damage fills up the Consuming Memories bar, and allies whose bar is full fall into Sleep, take increased damage, and gain the Dismay status, which permanently blocks Healing and Shields.

New Cookies
[LEGENDARY] Nether Queen Cookie

Nether Queen Cookie, the Master of Death and Oblivion who commands the sweet waters of Oblivion from the throne of Tartrus, has arrived in CookieRun: Kingdom. She is a Healing Cookie who uses the skill "River of Tartrus." The waters of Tartrus purify removable debuffs from allies, then restore HP and grant an HP Shield along with DMG Dampening and DMG Resist buffs — when her skill heals an ally beyond their Max HP, the excess is converted into a Shield. The skill inflicts Soul Shackling, Branded Soul, and Injury on enemies. Nether Queen Cookie gains Soul Fragments periodically and upon meeting certain conditions; once she has enough, she grants the Ring of Tartrus and its power to ally Cookies (excluding herself) just before they are defeated, triggering up to 2 times per battle — allies who already have other Immortality or Invulnerability effects active before being defeated are excluded. She is not affected by removable Incapacitated debuffs, Silence, Cooldown freezing, or Cooldown recovery reduction. At the start of battle she gains the Ruler of Tartrus buff and grants herself an HP Shield once while inflicting DMG and ATK reduction on enemy Cookies. If there is exactly 1 Healing Cookie on the team, she grants DMG Dampening and CRIT DMG Resist to herself. Once per battle, when defeated, she grants herself the Ring of Tartrus and her Cooldown is reset. If an enemy Cookie gains Invulnerability, it is removed after 1 sec.

[EPIC] Asphodel Cookie

Asphodel Cookie, a guide to lost souls wandering along the River of Oblivion, has arrived in CookieRun: Kingdom. She is a Bomber Cookie who uses the skill "Cat Ghost," summoning a Cat Ghost at the enemy's location that explodes after a set time, dealing damage. It deals extra damage to enemies in PvE, increasing with each Grass Cookie on the team (excluding herself), and additionally grants ally Grass Cookies increased CRIT%, CRIT DMG, Grass-type DMG, and DMG Resist.

New Features
Trials of the Nether Realm

Explore the Nether Realm — lead your expedition on the right path and go as far as you can. Trials of the Nether Realm is a seasonal endless exploration mode where designated Cookies explore the Nether Realm based on each season's featured element, across two difficulties: Easy, a relatively light challenge with a maximum of 5 areas, and Hard, a grueling challenge featuring an endless series of areas. Each season features 3 designated elements and expeditions can only be formed with Cookies using those elements, while Cookies featured each season receive powerful special effects. Additional expedition slots can be obtained from Area Clear Rewards and remain unlocked for your next run, and only one high-rarity Cookie (WITCH, BEAST, LEGENDARY, ANCIENT, DRAGON, or SUPER EPIC) can be placed per run. Choose your path at each fork and advance by selecting Battle Nodes (progress saved after each wave), Fierce Battle Nodes against elite enemies whose remaining HP is saved — and where an appearing Cookie enemy can be recruited to your party without taking up a slot — Healing Nodes that restore one Cookie's or the whole expedition's Activity Points, Rift of Oblivion Nodes that resolve at random, and Boss Nodes waiting on the final floor of each area. Cookies that participate in battle lose Activity Points and cannot fight again once out of AP until the run ends. Rewards come as Area Clear Rewards (a once-per-season First Clear Reward), Node Rewards at milestones, and Battle Rewards; after ending an expedition, Time Jumpers let you earn Battle Clear Rewards based on the deepest zone reached during the season, though those rewards do not count toward your score. Note that images in the patch notes were captured in a development environment, so values and some reward details may differ from the final version.

Star Collection

The new Star Collection system lets you earn various rewards and buffs depending on your Cookies' upgrades. Access Star Collection from Cookies > Bonds. Star Points are calculated separately based on each Cookie's rarity and grade and are automatically awarded based on the upgrades of your Cookies, and can then be used to obtain various buffs and rewards from the Star Collection.

Star Abilities

Star Abilities is a new system that allows you to unlock account-wide benefits in the Kingdom Arena by collecting and promoting Cookies of SUPER EPIC and higher rarities. Reaching certain Star Grades with a high-rarity Cookie unlocks new Star Abilities, and these effects apply only in the Arena. They are divided into Battle Effects, which apply only while the Cookie is on the team, and Passive Effects, which apply even while the Cookie is not on the team. There are three types: Star Power increases the Cookie's final DMG dealt, Star Guard decreases the Cookie's final DMG received, and Star Heal increases the Cookie's final Healing given and received. On the reasoning: differences in Cookie grades are not always meaningfully reflected in battle outcomes, as battles have become more fast-paced, some Cookies rely heavily on damage proportional to Max HP, and others excel by strengthening allies or hindering enemies rather than dealing ATK-based damage — meanwhile existing upgrade systems such as the Laboratory, Statue of Heroic Radiance, and Guild Relics have become more wide-spread, diminishing the impact of Cookie collection and promotion. Star Abilities are intended to ensure promotion retains a meaningful impact and lasting value regardless of whether a Cookie is currently in use. To keep upgrades noticeable without compromising strategy or competitive play, their scope is managed carefully: usage is restricted to the Kingdom Arena only, a significant portion of each Star Ability's power is provided through Battle Effects as soon as the Cookie is obtained so low-Promotion Cookies remain useful, and the effect improves gradually as values rise to prevent inflation from new Super Epic or higher releases. For example, at 500 Star Power final damage dealt increases by approximately 6%, and at 500 Star Guard final damage received decreases by approximately 15%.

Kingdom Affairs Portal

Grow your Kingdom in new ways, strengthen your Cookies, and usher in a new age of prosperity. The existing Kingdom Affairs feature is being split into the Play Portal and the Kingdom Portal. The Kingdom Portal brings together various features that contribute to Kingdom growth, letting you review them at a glance and jump directly to the relevant content — Star Collection, Cookie Bonds, Costume Sets, Star Ability, Statue of Heroic Radiance, Sugar Gnome Laboratory, Guild, and Landmarks.

Legendary Topping Tarts

Obtain Legendary Topping Tarts from the Trials of the Nether Realm and build an even stronger deck. Unlike existing Topping Tarts, Legendary Topping Tarts come with exclusive bonus effects: one of 11 bonus effects is applied randomly, and Tart Cores can be used to change it — when changing, one random effect other than the current one is offered and you may accept it or keep the current one, and the change does not alter the current Upgrade Level as the new effect's value is adjusted to match. Tart Cores are obtained by breaking down Legendary Topping Tarts or as rewards from the Trials of the Nether Realm, and are used to change bonus effects, upgrade Legendary Topping Tarts, and reset upgrades. Each Legendary Topping Tart has 12 upgrade attempts; succeed in all 12 to reach the maximum Upgrade Lv. of +12, with higher levels granting greater bonus effect values. Each attempt consumes one upgrade opportunity whether it succeeds or fails, and a failed upgrade does not increase the Upgrade Lv. and lowers the maximum Upgrade Lv. that can be reached. Tarts with failed upgrades can be reset: each has its own Reset count, and at certain reset thresholds the cost required for Enhancement increases. Resetting returns the Upgrade Lv. and used attempts to 0, and further upgrades receive an additional success rate that increases with each reset. You can also promote Epic Topping Tarts to obtain Legendary Topping Tarts — promotion retains the Topping Tart's type and stats while adding a new Legendary-exclusive bonus effect, and requires Butter Cream obtained from the Trials of the Nether Realm.

Pick and Choose Gacha

The new Pick and Choose Gacha lets you select the Cookie you want to obtain. You can use up to 5 gacha preview attempts for free each day, and use Crystals to purchase additional attempts. Up to 5 gacha preview results are automatically saved in chronological order, and if more than 5 are saved the oldest result is replaced by the newest one. You can select any saved result from your preview history at any time, and if a Cookie you want appears in a gacha preview, tap Confirm to obtain that Cookie for free. Cookies and Soulstones available by gacha slot: Slot 1 offers SUPER EPIC to WITCH Cookies, Slot 2 offers EPIC to WITCH Cookies, and Slots 3–10 offer COMMON to EPIC Cookies and Soulstones.

Costumes, Icings & Toppings
New Legendary Costume: The First Headmaster

Added a new Legendary Costume for Shadow Milk Cookie: The First Headmaster — get ready to meet the founding headmaster of Blueberry Yogurt Academy who once had an answer to every question.

Nether Queen Cookie and Asphodel Cookie will be able to equip these Toppings — check the Topping's details to see which Cookies can equip it. You do not have to equip Resonant Toppings exclusively for a set effect. Resonant Toppings have higher bonus effect values than regular Toppings, and their bonus effects might differ from those of regular Toppings.

Buff Time Rewards obtained every 5 min while in the Town Square are doubled. The maximum reward amount remains unchanged, while the time required to earn all rewards has been reduced from 2 hr to 1 hr under normal conditions. The Town Square Time Booster buff obtained by participating in Town Square Games now provides +10 min as opposed to +5 min.

Changes to Arena Grandmaster 3 and Elite 1 Requirements

The requirements for reaching certain Kingdom Arena tiers are being adjusted to make progression goals for higher tiers clearer. Grandmaster 3: top 0.5% of Master with 3,000 Trophies → top 1,500 overall with 3,000 Trophies. Elite 1: top 1% of Master → top 2% of Master. The requirements for reaching Grandmaster 1 and 2 remain unchanged, and the new requirements apply to Arena Seasons beginning after the update.

Arena Fast-Forward Improvements

The fast-forwarding condition in the Kingdom Arena has been adjusted: it is now based on your current highest achieved Tier.

Kingdom Optimization Improvements

The Resolution option in the Settings menu has been optimized to reduce device overheating, though slight pixel differences may occur on some high-end devices.

The way CRIT% values are displayed for Toppings and Topping Tarts is improved: values now show one decimal place instead of two.

Great Sage's Gem Balance Adjustments

Some effects of Great Sage's Gem have been increased. Team DMG Resist at the start of battle: +15% → +25%. ATK upon activating Immortality: +20% → +35%. DMG Resist upon activating Immortality: +15% → +30%.
